INJECTOR OF ARC SPRAYING PISTOL Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: resistant to wear nonconducting guide is made with the second channel for the passage of the second electrode located between the current lead and the point of the electrode passage in the current lead and the guide are not coaxial. The innovation concerns the equipment for applying the protecting coating with the method of electrostatic metallization. EFFECT: enhanced economy of the spray-coated material and of the electric power, ensured stable combustion of the arc at the increased length of the electrode escape. 2 dwg
